Even if they are lucky, if they do not have restrictions on gambling, they will only experience serious gambling problems.
I thought restrictions and limits actually reduce problems when it comes to gambling, if someone doesn't have enough self-control to stop gambling excessively, they might do that if there are restrictions from the casino itself due to regulatory pressure.
And of course, they have to comply with the limits they have made so that they can enjoy gambling as they should.
Limits in gambling are a good thing to prevent gamblers from excessive losses and getting addicted to gambling, it might specifically stop someone from getting addicted but it will at least reduce the effects.
And it doesn't seem like it's about an ethical issue because each country has its own regulations and if a country prohibits gambling, the government must have its reasons why they prohibit gambling. And if a country allows gambling, perhaps its government has considerations too. There may be other unstated reasons why these countries allow or prohibit gambling.
That's definitely true, a country wouldn't ban or legalize gambling with no reason at all, there must be some reasons, like religious prohibitions, legal consequences, environmental or societal issues, or anything else that might seem to go out of control and they need to take some actions against it.
